Review: Reliable high-torque RTV silicone — my husband’s go-to gasket maker - My husband picked up this Permatex 82194 Ultra Grey Rigid High-Torque RTV Silicone Gasket Maker for some repair projects. It does exactly what it’s supposed to — forms a strong, durable seal. What works well: • Stays flexible enough to handle vibration and temperature changes but cures rigid. • Good for making custom gaskets on oil pans, valve covers, water pumps, and similar automotive/equipment parts. • Easy to apply from the tube and cleans up nicely before it sets. • Trusted Permatex quality at a fair price for the 3 oz tube. He’s used Permatex products for years and this one performed as expected. Solid choice if you need a high-performance silicone gasket maker for mechanical repairs. Review: Works great to clean up a mess - Used Ultra Gray gasket maker on a job that was “definitely not that bad” and somehow leaking from everywhere. Slapped this stuff on, bolted it together, and now it’s tighter than my budget after buying tools I didn’t need. It sticks, it seals, and it doesn’t care how confident you were before you realized the gasket was toast. Oil stays in. Coolant stays where it belongs. No drips, no excuses. If you enjoy products that quietly make you look like you know what you’re doing, Ultra Gray is the hero you didn’t know you needed. Five stars. ## Features - Designed specially for high-torque and high vibration applications - Maximum vibration resistance, with outstanding resistance to oils, cooling and shop fluids - Low odor and non-corrosive formula - Suggested Applications: Valve covers, oil pans, intake manifold end seals, timing covers, water pumps, thermostat housings ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000HBGI8K | | Best Sellers Rank | #549 in Automotive ( See Top 100 in Automotive ) #2 in Gasket Sealers | | Brand | Permatex | | Brand Name | Permatex | | Color | Ultra Gray | | Customer Reviews | 4.8 out of 5 stars 5,591 Reviews | | Global Trade Identification Number | 00686226821942 | | Included Components | Unit^Instruction Guide | | Item Shape | Round | | Item Thickness | 5 inches | | Item Type Name | 599B U-GREY RTV | | Item Weight | 3.36 ounces | | Manufacturer | Permatex | | Material | Silicone | | Material Type | Silicone | | Model | 82194 | | Number of Items | 1 | | Part Number | 82194 | | Pressure | 5 inches_mercury | | Shape | Round | | UPC | 686226821942 686226001139 | | Unit Count | 3 Ounce | | Upper Temperature Rating | 500 °F | | Warranty Description | LIMITED WARRANTY | ## Product Details - **Brand:** Permatex - **Color:** Ultra Gray - **Item Thickness:** 5 inches - **Material:** Silicone - **Upper Temperature Rating:** 500 °F ## Images ![Ultra Grey - Image 1](https://m.media-amazon.com/images/I/811ISBbKpxL.jpg) ![Ultra Grey - Image 2](https://m.media-amazon.com/images/I/81KIFlXwFdL.jpg) ![Ultra Grey - Image 3](https://m.media-amazon.com/images/I/81i-psqQnHL.jpg) ![Ultra Grey - Image 4](https://m.media-amazon.com/images/I/81SMFyiPRBL.jpg) ![Ultra Grey - Image 5](https://m.media-amazon.com/images/I/71XPCTZTLBL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: Hello. Does this sealer is suitable for my scooter oil krancase gasket( to sealed it) ?** A: The Ultra Gray is the BMW Motorrad replacement gasket material for case applications. If it's recommended for BMW motorcycles it's probably great for a scooter. **Q: Can ultimate grey be used to hang a rear view mirror to the windshield. Mine falls off every few months.** A: I used high temp double sided epoxy tape. Wash the windshield and the mating surface on the mirror with detergent and rinse. Do not get any finger oil where you will be adhering. using 600 grit sandpaper, lightly abrade an area of the windshield that will be hidden by the mirror trim. Do the same for the mating surface. Apply the tape (or this adhesive) per manufacturer's instructions. Do it late in the day or in a garage so it's not in a baking car. Give it a chance to cure. If possible, bend a coathanger or something to give the mirror support while it's curing. **Q: can this be used on water pump Bolt threads?** A: You bet. Just follow the instructions on the tube precisely. **Q: Will it help on a valve cover gaskets?** A: Yes, just make sure you have a uniform thickness on the contact surface. I will usually only put it on the valve cover and not on the head. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reliable high-torque RTV silicone — my husband’s go-to gasket maker *by M***S on July 5, 2026* My husband picked up this Permatex 82194 Ultra Grey Rigid High-Torque RTV Silicone Gasket Maker for some repair projects.
